METAL RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 483,821, dated October 4, 1892.

Application filed MarohSO, 1892. Serial No. 426,997. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL H. WILSON, a citizen of the United States, residing at WVebster, in the county of \Vorcester and State of Massachusetts, have invented a new and useful Metal Railroad-Tie, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

The object of my present invention is to provide a metal railroad-tie of such construction that it can be economically and practically produced and which will efficiently meet the requirements of service.

To this end myinvention consistsin a metal tie having its parts constructed and combined in the peculiar manner herein set forth.

The particular subject-=matter claimed is hereinafter definitely specified.

In the drawings, Figure 1 is a side View of my improved metal railroad-tie. Fig. 2 is a plan View of one end. The opposite end is the same. Fig. 3 is a transverse vertical section, on a somewhat larger scale, at line a: 00. Fig. 4 is a plan View of the foot-plate. Fig. 5 is a plan of the cap-plate blank, and Fig. 6 is a transverse section of the foot-plate.

My improved tie'is constructed as follows:

The main body A is formed With an upright web having double-flanged top and bottom edges, as shown, or a sectional shape similar to a light I-shaped rolled iron beam. This body is longitudinally plain and straight, so that it can be readily rolled out in an ordinary beam-mill, and is of proper length to extend across the road-bed. Its ends are best out off diagonally, as at a a. Foot-plates B B, formed of flat sheets of metal about eight inches Wide by thirty-two inches long, more or less, are provided at the respective ends of the tie, each fitted with attaching-ears b of suitable shape for overlooking the bottom flanges 2 of the body. These foot-plates are arranged in horizontal position beneath the ends of the body A, centrally corresponding with the rail-seats, and are secured to the body by sliding them longitudinally onto the end with the ears embracing the flanges 2. A stud 3, inserted in the web, holds the footplate from being Withdrawn, or,if desired, the plates B can be put onto the body while hot and the ears set down and shrunk onto the flanges by cooling.

C 0 indicate caps or rail seat plates about eight inches square, more or less, which rest upon the top of the body and are confined thereon by clips or ears 0, that embrace the flanges 4 in similar manner to the footplates.

D D indicate wooden blocks that rest on the cap-plates O and form the seats for the track rails F, which are fixed in place by bolts 6, that pass through the plates 0 and body flanges 4, suitable washers and nuts m being provided therefor, so as to afiord a firm and secure connection.

The cap-plate O is best provided with up wardly-projecting lugs 5 on their edges, that serve as guards against the foot of the railF and to retain it from lateral displacement on its seat. This plate also has a flange 6, that serves as a guard for the block D. The cap plates are preferably made from sheet metal cutin the form shown in Fig. 5, and thelugs and flanges bent upward by suitable means. The ears 0 and b of the plates are best out and struck up from the sheet or rolled plates in the manner illustrated. The inner end of the foot-plate B can, if preferred, be turned downward, as at B, to afford a hold uponthe earth against endwise drift of the tie.

By the construction herein shown and described I provideavery desirable and efficient metal tie that can be manufactured with practical facility. The parts of the tie can be readily produced by simple rolling-mill op erations, the cars can be readily formed in dies, and the parts can be quickly assembled at the works or used by sliding the plates B and C endwise onto the body-flanges, thus producing the article with littlelabor and expense.

. I am aware that metal ties of difierent construction have heretofore been made; also, that wooden blocks have been employed as rail-seats in metal ties. It will therefore be understood that I do not claim such features,

broadly, but that my invention relates to the improved structure, substantially such as defined.

I claim as my invention herein, to be secured by Letters Patent- 1. The within-described metal railroad-tie, consisting of the I-shaped body-beam, the horizontal foot-plates and cap-plates attached to the respective ends of the body by ears that are punched through and set out from the plate metal and formed to embrace the bodyfianges at opposite sides thereof, substantially as set forth, 7

2. In a metal railroad-tie, the combination, substantially as described, of the body composed of a straight rolled I-shaped beam with diagonally-formed ends, the horizontally=disposed foot-plates having attaching-ears that overlook on the body-flanges, the cap-plates having attaching-ears that embrace the top body-flanges and provided with upwardlyprojecting guard-lugs, and the rail-seat blocks, for the purposes set forth.

3. In a railroad-tie, the combination, with the straight bodyhaving the upright web with SAMUEL H. WILSON.
